Honestly I dont recall there being much wind that day maybe a little breeze. The shooting lanes at this particular range have trees on either side going down range so it is kind of protected from the wind. It very well may be my technique I recall coming close to a seize fire so i through the last 3 being 45 grs down range rather quickly. It would really be nice if I can get that amount of vertical with very little horizontal so I am going to load some more up this week between 44.5 and 45 possibly 3 of each at .1 gr increment to see what that yields. And definitely take a little more time to practice better technique. This new barrel is really showing some promise. Thanks for the reply I was just thinking it was a little odd how the horizontal became so far apart with seemingly only a powder charge as being different, was thinking that it would be more of vertical spread over horizontal to look out for.
